I was tidying up the wiring inside the enclosure of my cnc mill when I experienced a shot curcuit that took out the breakout board. I ordered and installed a new breakout board and installed it. The X-axis worked normal. The Y-axis did not work at all. The Z-axis worked but it traveled in the same direction when either up or down button was pressed. If I unplug the X-axis motor and plug in either the Y or Z axis motors into the control for the X-axis they work correctly.
The controls for the breakout board are fed through a parallel port. With the parallel port unplugged and the power to the breakout board and stepper drivers turned on I get the same result. The X-axis motor locks up but not the Y and Z axis motor do not.
The electronics supplier where I got the breakout board thinks that the short circuit may have shorted the parallel the parallel port. But I think it seems that the breakout board is faulty seeing that I have the same symptoms whether the parallel port is plugged in or not.
I would appreciate your thoughts and comments.
